Hi,
Theres a possibility that the tac switches of your unit got stucked thats why your units function is intermittent. Try to have your buttons removed and have your units circuitry be resoldered.

MY ILIVE SOUND BAR KEEPS TURNING OFF WHEN WATCHING TV


I'm having the same problem. I don't think it has anything to do with the Sleep settings, you can play with them all day & the only benefit you may get is forcing it to stay on for 90 min or whatever instead of 15.
(I've tried setting to 00, obviously the first thing that comes to mind is that it's a Sleep Setting issue, but I seriously doubt this. You can't even set the Sleep Setting to 15min anyway)

Instead, I'm pretty sure that the problem exists in the sound bar not recognizing that there is an active signal & is shutting off due to what it sees as inactivity (timing out after use). I've come to this conclusion due to multiple complaints of the same problem.

Some people are reporting that it's not happening when they watch movies, others have tested & said the radio stays on as long as you like, a couple people have posted that theirs works fine & only shuts off when they turn off about 15 minutes after they shut off the audio source, which leads me to think that this is what is going on, the system thinks the audio source (TV, Bluray, etc) is off & no sound is coming through. It must have a funny way of detecting it...

I will try a few tests & if anything works I will pay the results. One person claimed there's stayed on after turning their TV all the way up... I could try this but will have to turn TV speakers off (currently I am running both TV speakers & sound bar). Anyway, I'll keep digging, must be some way to get this to work, I hope...

TV keeps shutting off. It will stay on a few minutes when cold but then will shut off. When we turn it on again after its warm it shuts off and won't stay on. Could something in menu bar have been changed...


It looks like a power supply SMPS problem.

You have to replace the optical isolator in the SMPS feed back circuit. It is a 4 pin IC
Mostly this may be the problem. Take the help of the service personnel.

My base unit keeps shutting off after about 8 minutes. Sometimes it comes on in a minutes and other times it must be reboot (unplugged.) Is it defective?


I just had the same issue - i've had them for about 18 months and they were working fine with my regular tv set - connected the red/white analog plugs to the back of the tv and then other 3.5mm end to back of base... but now, i just bought an LG hdtv and had to reverse that connection... 3.5mm to the tv and the analogs back to the base... worked ok for about 10 mins then the base shut off... seems that the volume setting on the hdtv wasnt up high enough to "register" with the base - base thought nothing was happening so it automatically shut off for "inactivity" - so, when plugged into tv, I turned the tv volume way up to 100.... seems to have worked - just need to be sure to turn the volume on the tv back down before removing the headphone jack!

My TV won't stay on until it's warm?


have your unit power supply check, maybe some cold solder or leaky capacitor is the culprit.

The tv keeps shutting off just after minutes of turning it on. We can wait about 5-10 min before turning it on again but then it only stays on for a few minutes.


This sounds like a heat related problem, which could be a faulty chip or a cold (bad) solder joint on one of the PCBs (printed circuit boards). Due to the lethal voltages present inside a CRT type television, it is strongly advised to have this repaired by a qualified technician. however, if you or someone you know is technically inclined, you can try to fix this yourself. Cold solder joints can often be spotted by visible cracks in the solder joints. a through inspection of all the boards could easily identify the problem which can be resolved with a quick tap with a soldering iron and perhaps a little extra solder added to the joint. if that yields nothing, another method is heat/cold stressing the boards while the TV is running. With the TV on, spray small areas of the PCBs with cold spray (or a can of compressed air duster turned upside down) until the tv shuts off. then heat the last sprayed part with a hot air gun (or a hair dryer) until you can get the problem to repeat regularly. inspect the area causing the problem and you will probably find the culprit.

TV shuts off on it's own. Turns on fine, stays on for a few minutes, then something clicks inside, and it shuts off, and can't be turned on with remote. I then spend the next 5-10 min turning it back on...


This is because of a power supply unit going out inside and there is not much you can do accept for have it repaired or think about new at this point also with the new digital tv standars comming out you are going to need a box for this if you doing OTA anyways so at this point if you are not inclided to haing it repaired have it recycled.
